.SPYING APERTURE FOR DOORS, WALLS, AND THE Specification of LettersPatent.

Patented Feb. 4, 1908.

Application filed August 6. 1907. Serial No- 387.353

To all whom it may concern:

Be it known that I, JOHN SHAoKLEY, subject of King of Great Britain,residing at Whitehaven; in the county of Cumberland, England, haveinvented certain new and useful Im rovements in S ying A ertures forDoors,%Valls, and the Li e, of w ich the following is a specification.

This invention contemplates certain new and useful improvements inspying apertures or devices for doors, walls or the like, so that, forinstance, a householder may see the person at the door Without suchperson seeing the one inside, before opening the door, so as todetermine whether or not the door shall be opened.

The invention consists essentially of a pair of devices designed to befitted within openings in a door, wall or the like, said devices beingprovided with glass or lenses through one of which the person inside mayview the person outside without himself becoming seen, and at the otherof which there is desi ned to-be placed a light of any character W ichwill shed its rays through the latter device upon the person outside sothat such person ma be seen at night.

With this and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arran ements and combinations of the parts that T shall hereinafterfully describe and then point out the novel features in the ap endedclaims.

For a and the merits thereof and also to acquire a knowledge of thedetails of construction and the means for effectin the result, referenceis to be had to the folfbwing description and accompanying drawings, inwhich:

Figure 1 is a perspective view illustrating the applicatign of myinvention to a door.

Fig. 2 1s a transverse sectional view of a door equipped with theinvention. Figs. 3 and 4 are similar views of modifications hereinafterspecifically referred .to.

Corresponding and like arts are referred to in the followin descriptionand indicated in all the views 0 the drawings by the same referencecharacters.

Referring to the drawin the numeral 1 designates a door, which I aveselected for the purpose of illustration, although it is to beunderstood that my invention 18 e ually applicable to walls and thelike. The door 1 is provided with two openings 1 and 1", that 11understanding of the invention and which is normally closed by an opaqueshutter or disk 5 which may be swung or otherwise moved away from theopening and which in the present instance is shown as pivoted at 6.

The illuminating aperture or device comprises a front plate 7 which. maybe similar to the front late 2 and which is preferably countersunr inthe door at the front of the opening 1". A lens 8 is held in the openingby the front plate. 9 designates the back plate of this opening. Areflector 10 is set ack of the opening 1 and is preferably provided onits lower side with a segmental rim 11 formed with an arm 12 by whichthe reflector may be secured to the door.

13 designates a smoke guard which in the present instance is in the formof an angular plate, one member of which may be slipped back of the ed eof the back plate 9 so as to frictionally'hold the smoke guard in properposition to protect the woodwork from the illuminant held between thereflector 10 and the opening 1".

From the foregoing description in connection with the accompanyingdrawing, it is obvious that a person may hold a light of any characterin front of the reflector and thereby throw the rays upon a personstanding outside of the door, wall or the like, while. at the same timethe-person inside may view the 'person outside by merely moving theshutter 5 away from the opening 1. Obviously the erson outside cannotview the person inside during this operation. By this means it will beseen that I have provided an efficient device which, as an examle, willbe a large measure of protection to liouseholders, as they canscrutinize visitors before opening the door, and thus protect themselvesagainst possible insult and inury, or annoyance.

The spying device, as well as the illuminating device, may be made indiversified ways, and the parts variously arranged.

For instance, as illustrated in Fig. 2, a ring 14 may be provided toreceive the glass or lens, said ring being provided with an inturnedflange 15 extending around the glass or lens and with an outturnedflange 16 which may be secured to the front plate 2 by means of thecurled over edge 17 of the latter. Asillustrated in this view, an outertube 1.8 is fastened to the ring 14 and is provided with interiorthreads designed to engage the exterior threads of the tube 19 whichfits snugly in the opening 1 and which is secured to and forms part ofthe back plate 4.

Fig. 3 illustrates a modification in which 20 designates the frontplate. This front plate is provided with bosses 21 in which tie rods 22screw, said tie rods also extending through the back plate 23. T hefront plate 20 is provided with a shoulder 20 against which the glass orlens 24 abuts, the said glass or lens being held in place by a ring 25screwing in the front plate from the rear.

Fig. 4 illustrates another modification in which the front plate 26 isprovided with a rearwardly extending flange 27 within which the glass orlens 28 is mounted, 29 designating a ring screwed into the flange 27 tose cure the lens or glass in place: The flange 27 is exteriorly threadedalso and is engaged by the interiorly threaded tube 30 formed integralwith or secured to the back plate 31. In this form, in order to preventthe front plate from turning while the back plate is being connectedthereto, the said front plate is provided with a pin 32 embedded in thedoor or like structure to which the device is applied. It is obviousthat the front and back plates maybe of such size as to support both thespying device and illuminating device,

and that the illuminating device may be placed either above or to oneside of the spying device, as judgment may dictate. When theilluminating device is placed to one side of and on a line with thespying device, the former should be so adjusted that the rim of thereflector will protect the light from the eyes of the person spying out,and the smoke cap should be tilted or moved to proper position toprotect the door.

The interior of the spying device should preferably be painted orotherwise made solid black, as well as the front side of the shutter, sothat'the person outside-may not see the movement of the shutter to theopen position, and the reflector should, of course, be kept bright.

Having thus described the invention, what is claimed as new is:

1. The combination with a door, wall, or the like, provided with twoopenings extending therethrough, of a glass held in one of saidopenings, a removable closure secured to the door or the like at therear side of said opening, a lens held in the other opening, and areflector secured to the door or the like at the back of said last namedopening and spaced therefrom, said reflector being formed at its lowerside with a segmental rim.

2. The combination with a door, wall, or the like, provided withtwoopenings eX- tending therethrough, of a glass held in one of saidopenings, a removable closure for the rear side of said opening, a lensheld in the other opening, areflector at the'rear side of the last namedopening and spaced therefrom, said reflector being formed at its lowerside with a'segmental rim, said rim being formed with a downwardlyprojecting arm secured to the door or the like, a back plate secured tothe door at the rear of the last named opening, and an angular plate,one' part of which is adapted to be slipped back of the edge of saidback plate into frictional engagement with the same and the rear face ofthe door, over the reflector.

In testimony whereof I aflix my signature in presence of two witnesses.

JOHN SHACKLEY.
